.M AC HlNE FOR MAKING CARPET-LINING.

SPECIFICATION forming part of v Letters Patent No. 244,496, dated July 19, 1881.

V Application filedJune 10, 1881. (No model.)

To all whom. it may concern:

Be it known that I, CHARLES K. STINsoN, a citizen of the United States, residing at New York, in the county and State of New-York,

have invented certain new and useful Improvepaper secured at uniform intervals to a plain continuous sheet of paper, the grooves or corrugations being filled with cotton or other suitable material, and the edges finished by lapping the lower paperover and upon thenpper to make a closededge.

In the accompanying drawings, which serve to illustrate my invention, Figure l is aview, in side elevation", of myimproved machine, and Fig. 2 is a sectional View of the lining which my machine is designed to manufacture.

A is the main body of the frame of thermachine, which is shown as constructed of piping or tubing of requisite size,jointed in any wellknown way, and within which is mounted in suitable bearings the feeding, cardin g, and cutting mechanism. I

B B are rolls of paper hung in bearings a a. The two together form the envelope or covering for the lap, the paper from the roll B, after passing through the paste-rolls, taking the strips or sections of the-lap as they fall from the cutting-roll and bearing them onto the heated corrugating-rollers, where it meets the paper from roll B as it passes out'from between said rolls, and thence the whole is carried on, beneath the lower corrugated roll, to the drying-cylinder.

A is that portion of the frame which I designate as the scratcher-frame. Within this is arranged the mechanismfor forming the cotton in a continuous lap or bat. From the lapracks C C and strainers the cotton is (leliv ered to the scratchers E E by feed-rollers F F, and thence onward to the revolving screens Gr G, from which point it is carried by suitable ways or aprons in a continuous lap to the cutting and compressing roll. The scratchers E E, and the mechanism acting in conjunction with each, are arranged at different elevations within the frame, and each scratcher Works independently, so that a double lap is thrown, each lap as it comes from its respective scratcher being one-half the thickness, and the two distinct laps unite after leaving the screen G G, and a lap of the desired thickness is delivered to the cutting and compressing roll. By this arrangement I am enabled to work the cotton much faster than is possible where one lap only is thrown, as is the case where but one'scratcher is used.

The paper from the roll B, which serves for the under side, is about two inches wider than the paper on roll B, to enable it to be lapped or folded over the edge of the corrugated surface, as will be more fully set forth hereinafter. This paper is passed between the paste-rolls b, which are fed by doctor-rolls b suitabl y arranged within a paste-vessel, c, in the ordinary manner, and on and over the endless apron H.

The apron H- passes around suitable bearing:

rolls, d 01, arranged within the main frame of the machine, and is caused to press closelyup to the cutting-roll, so that the paper may readily take the strips or sections of the lap as they are cut off.

One or morecutting-blades, c, are set in or otherwise secured to the peripheryof the roll V I. Beneath this roll I is hung a bearing-roll,

J, its surface coveredwith any material suitable for the blade to cut on. As the lap passes between these rolls it is cut crosswise into strips or sections, of a width adapted to the corrugations in the paper which is designed to inclose such sections. These strips as they come from the cutting-roll are caused to fall upon the paper at uniform distances apart, and this spacing I accomplish by a positive independent rotary motion of the paper-carrying mechanism, the adjustment being such as to cause the paper to travel with a velocity exceeding that of the lap, and the spaces between the lap-strips may be increased or diminished by accelerating or retardin gthe speed of the paper relatively to that of the cuttingroll. After receiving th'elap-strips the paper passes beneath the corrugated rollers K, which are delivering the paper from roll B in a corrugated form, and the whole is submitted to pressure beneath said roll, the upper paper inclosing the laps and being secured to the under paper" between each section, presenting the appearance shown in Fig. 2. From thence the finished lining is passed over and between heated rolls and pipes, as will now be described.

The corrugating-rolls K K are hollow steamheated drums arranged to rotate in bearings f, the lower one, K, pressing hard against the cylinder L and endless apron H. The dryingcylinder L is constructed of a continuous coil of pipe, and provided with suitable means for admitting steam at one end of the coil and exhausting it at the other.

9 g are the spokes or arms of the cylinder, of similar piping, and h is a piping-shaft having its bearing in the cast-iron box t, which is chamfered out and packed at each end. Steam is admitted to the cylinder at the valve j, passes through the vertical pipe 70, into the hollow bearing i and shaft h, and thence through the arms 9 into the cylindrical coil, and on and out by a similar arrangement on the other or opposite side.

M is a piping-shell, which is secured to the frame of the machine, and which incloses the cylinder L. Itis placed about oneinch therefrom, affording sufficient room for the lining to pass between it and the cylinder. Steam is admitted through valves suitably arranged therewith. After leaving the corrugating-roll K the lining passes over the cylinder L to the folder or hinder an arranged on the shell M, which is adapted to turn the edge of the lower paper over and upon the upper one, and thence on and between the solid roll N, which presses the edges of the fabric closely together. It then passes between the cylinder and the hollow steam-drum 0, provided with a corrugated surface to fit the corrugations in the lining, and from thence encircles the cylinder L until it reaches the roll at, around which it is passed, and thence carried in a reverse direction around the outside shell, M, and over the roll 0, through the marking-rolls pp, to the folder or receivingbox q.

By constructing the drying-cylinder with an outside steam heated shell I am able to get double the amount of drying-surface without much increase of space.

The roll 0, as stated, is a hollow steamdrum geared to the cylinder, its surface being corrugated, and this likewise greatly facilitates the drying of the upper or corrugated surface of the fabric.

In my present construction I have shown the frame of the machine as all constructed of piping, which may vary in size from one and a half to two inches. The arches Z 1, within which the roll 0 and marking-rolls p p are mounted, may likewise be made of similar piping.

Beneath the scratcher-frame is arranged a blower, s, in the usual manner, to facilitate the passage of the cotton flock by creating a draft from underneath it.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a carpet-lining machine, of double scratchers and screens, conjointly with the usual lap-forming mechanism so arranged as to work independently of each other, whereby a lap of one-half the desired thickness is thrown to the cutting-roller from each screen, substantially as herein shown and described.

2. The combination, in a carpet-lining machine, of a cutting and compressing roll to take the continuous lap as it comes from the scratchers and cut it into sections, pastingrolls to apply paste to the lower paper, an endless apron to carry said paper in proper conjunction with the cutting-roll to receive the sections of the lap as they are cut off,and corrugating and compressing rolls to corrugate the upper paper and compress the whole together, substantially as set forth.

3. The mechanism for securing the sectional laps on the continuous sheet of paper at uniform distances apart, which comprises a cutting and compressing roll, an endless apron, and corrugating and compressing rolls, the said parts being so arranged relativelyto each other that the speed of the apron is greater than that of the cutting-roll, as and for the purpose set forth.

4. The combination, with the cutting and compressing roll and endless apron running at a greater speed than said cutting roll, of steam-heated corrugatin g rollers adapted to corrugate the paper for the upper covering and secure it, at points between the sectional laps, to the lower paper, substantially as herein shown and described.

5. In a carpet-lining machine, the combination, with mechanism for forming the lining, of a drying-cylinder constructed of a continuous coil of piping having suitable supplypipes for the admission of steam, and provided with an outershell of piping, wherebya double heating-surface is provided, as and for the purpose described.

6. The combination, with the drying-cylinder, of a folder or binder, m, pressure-roll N, corrugated steam-drum O, and roll n, all arranged and operating substantially as described.

7. The combination, in a carpet-lining machine, with mechanism for forming the lap, of a cutting and compressing roll, paste -rolls, corrugating and compressingrolls, binder, drying-cylinder, with bearingrolls arranged to work in connection therewith, markingrolls, and folder-box, all constructed to operate in the manner herein shown and described.
